Roamio stream to PC?

I currently have my XL4 hooked up to a Slingbox. This allows me to stream HD to both my iPad and PC over my home network.

Have a Roamio on order which should arrive a the end of the week. I know that the Roamio can stream to my iPad but what about the PC? Do I need to keep using the Slingbox in order to maintain that capability?
